Very cool, thanks a lot :-)

If the pkg-config executable hasn't been found, pkg_check_modules() does 
nothing, right ?

FindExiv2.cmake:
set(EXIV2_MIN_VERSION "0.12")
is only in the NOT WIN32 branch, right ? I think at least the setting of this 
variable shouldn't be limited to non-Windows.

FindKIPI.cmake: is KIPI_FOUND set here directly after the results from 
pkg-config, i.e. not by checking the results of the find_path/library() 
calls ? This should be changed. Can you please also have another look at the 
other files whether this is the case there ?

Looking Ok: 
FindGLIB2.cmake
FindKdraw.cmake
FindKexvi2.cmake
FindPopplerQt4.cmake
